Hmmm... Weird
I'm running FG2.10 for almost 2 years and TNCM was the first extra scenery installed and it worked like a charm. However I had the same issue with clrCoda where the ND is useless. I had not update to FG3.0+ because I am not liking the way the controls are so I stayed at FG2.10 when FG3.0+ launched. In fact, I did give it a run but my poor laptop lagged like 10fps
